Polanyi, M., Discussion of the Potential Theory of Adsorption in Adsorption of Gases and Vapors, by Stephen Brunauer, Princeton University Press, Princeton, N. J., 1947. 

We are indebted to Stephen Brunauer, Rulon E. Johnson, Paul Seligmann, and Y. C. Wu for interesting and instructive discussions, suggestions, and penetrating arguments. We do not imply that all of our arguments are in complete agreement with the opinions of each of these scholars. 

We express appreciation to T. F. Young and to Stephen Brunauer for many helpful discussions and constructive criticism. We are indebted to Conway Pierce for suggestions improving our experimental techniques, and to Robert Landgren and Fletcher Klouthis for aid in preparing this manuscript. 

The distinguished career of Professor Paul H. Emmett has spanned six decades, beginning with his Ph.D. research under A.F. Benton at the California Institute of Technology in 1922. His pioneering contributions to the field of catalysis have provided the foundation for much of the present-day work in the field. Among his most notable contributions is the BET method for determining the surface area of solids, done in collaboration with Stephen Brunauer and Edward Teller. Surface area measurement by the BET method is probably the most widely used characterization method in catalysis today. 

Editor s Note In 1979, on the occasion of the one hundredth anniversary of Einstein s birth, the Washington Academy of Sciences held two commemorative meetings. Stephen Brunauer was one of the invited speakers. The talks were subsequently published in the Journal of the Washington Academy of Sciences, 69 3, 108-113, 1979 (Lancaster Press, Lancaster, PA, journal publisher). 

One of my students in these first classes was a fellow Hungarian, Stephen Brunauer. He worked in a place that was unofficially called "the fixed-nitrogen lab," more formally named the Bureau of Chemistry and Soils. 

BET Stephen Brunauer (1903-1986) was born in Budapest. Paul Emmett (1900-1985) was bom in Portland, Oregon and was in the same Ph.D. class as Linus Pauling. Edward Teller, also born in Hungary (1908-2003), is also known for his work in physics. 

BET Isotherm The Langmuir isotherm does not consider adsorption beyond a monolayer. Multilayer adsorption was treated by Stephen Brunauer, Paul Emmett, and Edward Teller (Brunauer, Emmett and Teller, 1938, see box) and named after the initials of their surnames as the BET theory. The BET theory is an extension of the Langmuir theory to multilayer adsorption with the following hypotheses AadsHmon is the enthalpy of adsorption for the first monolayer, AadsWr is that for the second and higher layers, and the Langmuir theory can be applied to each layer. We then have ...
